DLA-2391-1 ruby2.3 -- LTS security update

Date Reported:

01 Oct 2020

Affected Packages:

ruby2.3

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2020-25613.

More information:

A potential HTTP request smuggling vulnerability in WEBrick was reported.

WEBrick (bundled along with ruby2.3) was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsistent interpretation between WEBrick and some HTTP proxy servers, which may allow the attacker to “smuggle” a request.

For Debian 9 stretch, this problem has been fixed in version 2.3.3-1+deb9u9.

We recommend that you upgrade your ruby2.3 packages.

For the detailed security status of ruby2.3 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/ruby2.3
